A client of mine had done a DIY hair color at home herself and it turned out a little bit too dark. Rather than destroying her hair with a color remover of bleach to lighten it, we first did a Malibu C Crystal Gel shampooed with Malibu C Un-Do-Good Shampoo then applied Malibu C CPR and processed under heat for 25 minutes, shampooed three more times with Un-Do-Goo followed by Malibu C Miracle Repair. Her hair was light enough with only one application of CPR and felt amazing even though we had shampooed her hair several times. Thank you for giving me a safe alternative for the hair rather than stripping out the color harshly. Truly amazing products. Thank goodness for Hairstylists Diversity University or I wouldn't have ever known how amazing these products are.
